My '98 came with backless folding chairs, never used.
I put them in a garage sale and nobody was interested, while the first thing that sold was a goofy looking moving skeleton mirror Halloween decoration. Go figure.
You might put them on craigslist for local pickup, and with each passing week, reduce the price till they're free. I don't see anyone paying enough to ship them, considering how expensive shipping has gotten recently. Anyone willing to pay shipping can have mine for free. Wait, that's if I still have them, it was an uncle's garage sale and I don't know what happened to them, just that I was told they didn't sell.
